Abstract (en)

The present disclosure relates to a compressed core (206, 306) and a manufacturing method thereof. The method includes bundling optical transmission elements (202, 302) to form a core (206, 306), compressing the core (206, 306), extruding a sheath (212, 312) around the compressed core (206, 306). The core (206, 306) is compressed to a smaller diameter by a compression tool with a cylindrical cavity. And, the core enters from the first end of the compression tool with a diameter d and exits from the second end with a diameter d-Δd, such that Δd/d is greater than or equal to 0.05.
